Measure
Phase1: Liberal
Relapse/non-responder defined as having 5 or more heavy drinking days in the first 8 weeks of treatment otherwise the subject was considered a responder. Naltrexone: 100mg/day, up to 8 weeks during Phase 1, 16 weeks in phase 2.
Phase1: Stringent
Relapse/non-responder defined as having 2 or more heavy drinking days in the first 8 weeks of treatment otherwise the subject was considered a responder. Naltrexone: 100mg/day, up to 8 weeks during Phase 1, 16 weeks in phase 2.
Phase2: Responder - Naltx (Usual Care)
Phase 2: Naltrexone and TAU for phase 1 responders. Naltrexone: 100mg/day, up to 8 weeks during Phase 1, 16 weeks in phase 2.
Phase2: Responder - Naltx+Phone (TDM)
Phase 2: Naltrexone and telephone counseling for responders. Naltrexone: 100mg/day, up to 8 weeks during Phase 1, 16 weeks in phase 2. Telephone Counseling: Bi-weekly telephone calls lasting 15-20 minutes focused on the same content as MM.
Phase2: Non-responder - Naltx, MM and CBI
Phase 2: naltrexone, Medication Management (MM) and Combined Behavioral Intervention (CBI) for non-responders (NR). Naltrexone: 100mg/day, up to 8 weeks during Phase 1, 16 weeks in phase 2. Medication Management (MM): Brief manual-based therapy for up to 8 weeks during phase 1, 16 during phase 2. Combined Behavioral Intervention (CBI): 45-60 minute sessions with a certified therapist focused on resolving ambivalence and skill building. Number of sessions guided by achievement of goals identified within treatment plan; minimum 9, maximum 20 sessions over 16 weeks.
Phase2: Non-responder - Placebo, MM and CBI
Phase 2: placebo, Medication Management (MM) and Combined Behavioral Intervention (CBI) for non-responders (NR) placebo: placebo comparer for 16 weeks in phase 2. Medication Management (MM): Brief manual-based therapy for up to 8 weeks during phase 1, 16 during phase 2. Combined Behavioral Intervention (CBI): 45-60 minute sessions with a certified therapist focused on resolving ambivalence and skill building.
